frame, insuring the exclusion of flies and in- 10 sects, when in use.

A further object of the invention is to provide locking means for securing the screen in its adjusted position.

Another object of the invention is to provide a device of the .above-mentioned character which is simplev and durable in construction, reliable and efficient' in operation and inexpensive to manufacture.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

In the drawings, wherein for the purpose of illustration I have shown a preferred einbodiment of my invention, the numeral 5, denotes a window frame or casingihaving a pair of longitudinal strips of metal 6 and 7, secured to each side ofthe frame, in superposed relation, strips, at their upper ends have brackets 9 and 10 projecting outwardly therefrom, in which the spring roller 11 ismounted. The spring roller consists of a metal cylinder 12 having bearing blocks v each end and is iixedly connected to the block 13 by the pin 15, extending therethrough. Trunnions 16 and 17 extend inwardly from the center of the blocks, adapted to receive the ends of the tube 18, disposed axially of 24 in its'edges, as shown in by the screws 8. The top- 13 and 14 fitted in 1926. Serial No. 107,149.

the cylinder 12. The trunnionil is ixedly' connected with the tube by the pin 19 and a coil spring 20 is mounted on the tube having one end ixedly connected. to the tube and its opposite end connected with the bearing block 13, as at 21. The outer face of the block 13 has a pin 22 projecting centrally therefrom, which is journaled in a recess formed in the edge of the bracket 10. The block d4 has a pin 23 extending therefrom, of rectangular shape in cross section, having recesses Fig. 6, to establish a fixed connection with the recess formed in the bracket 9, whereby the block 14 and tube 18 will be held against movement. f To rprevent accidental displacement of the pins,

25 is secured to each strip an angular plate 6, as at 26, extending along the side of thev brackets and having bifurcations 26 t0. receive the pins, the ends of the bifurcations being bent to form alined ears 27 disposed in front of the brackets, adapted to receive the locking pins 28.

A sheet of flexible wire cloth 28 oi; other suitable screening material, of a width and length corresponding to the width and length of the window frame, has one end secured to the cylinder 12, by the spurs 29, struck upwardly therefrom, as shown in Fig. 3. facing strip 30 of suitable flexible material 'extends'along the longitudinal edges of the cloth, being folded around the wire cord 31 and riveted to the cloth, by the staples 32, as clearly shown in Fig. 7. This provides a beading 33 along the edges of the cloth, adaptv ed to slide in the guide slots 34, formed along theinner marginal edges of the strips 6 and 7, below the brackets 9 and 10, by bending the edges of the strips in opposite directions, as at 34 and 35. l

A facing strip 36 extends along the lower edge of the wire cloth and extends a substantial distance below the edge thereof, being formed of two sections, which are bent in opposite directions to form a cylindrical sleeve 37, extending transversely of the window frame. A tube or locking member composed of sections 38 and 39 is slidably mounted within the sleeve, the sections being normally moved in opposite directions by the spring 40, mounted intermediate thereof and bearing against the ends of the sections. 'As' shown more-clearly in Fig. 5, each section of the tube is fitted with a block 41 having finger clips 41', removably connected therewith by screws 42 which extend through openings 42 in each side of the sleeve 37, and the blocks are secured to the sections of the tube by set screws 43. One of the blocks has a tenon 45 adapt/ed to lit within the other section of the tube, for guiding the movement of the sections. A plug 46 is itted in the outer end of each section of the tube having a flat lug 47 extending therefrom, adapted to move in the guide slots 34 and engage openings 48 formed in the bent edge 34 of the top strip 6, `at spaced intervals for holding andlocking the screen in its adjusted position. A piece of canvas or other suitable material 49 is secured between the lower edges of the facing strip 36, as at 50, to establish a close fit between the sill of the window frame and screen, when the latter is in use.

In order to keep the wire cloth close tothe window a rubber roller 51, having a hollow metal core 52, is mounted in the brackets 9 and 10, below the spring roller, by the screw bolts 53, journaled in the openings 54 in the brackets and having threaded engagement with the bushings 55, in the ends of the core 52. A bearing plate 52 extends transversely of the window frame, under the wire cloth and roller, spacing the cloth from the frame.

A casing 56 completely encloses the spring roller, being of substantial-ly semi-circular shape in cross section, and is composed of two sections 57 and 58, telescopically connected together, to permit adjustment of the casing, with respect to the window frame. The rear wall 59 of one of the sections 57 is attached to the window frame, by the screws 60.

In operation it will be seen that the wire cloth or screen is constantly under the tension of the spring roller so when the screen is in use it is held taut. Locking members secure the screen in its adjusted position, which may be readily released from either side of the window. A close fit is established between the edges of the screen and the window frame, by the guide strips. so as to absolutely prevent the entrance of flies when the screen is in place. The spring reller is enclosed in a casing and the tension of the spring is'suflicient to tightly wind the screen thereon, so when not in use it will not mar the appearance of the window.

.lt is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that certain changes in the shape, size and arrangement of the parts may be made without departing from the spirit of the invention or the scope of the subjoined claims,

Having thus described my invention, I claim: Y, y

1. The combination with a rolling window screen having a rbeading formed along its longitudinal edges, and locking members mount-ed transversely of the lower end thereof, of guide-ways attached to the sides of a window frame, each composed of superimposed s'trips, the upper strip having its inner edge bent outwardly and inwardly to provide a longitudinal slot between the strips to receive the beading ,and ends of the locking members, the outwardly'bent portion of the upper strip having a series of openings in the guide-way to receive the ends of said locking members.

2. The combination with a rolling window screen having a beading formed along its longitudinal edges and locking members mounted"transversely of the lower end thereof, of guide-ways attached to the sides of a window frame comprising superimposed strips having their inner edges disposed in spaced relation forming longitudinal slots to receive the beading and ends of the locking members, said upper striphaving a se ries of openings in alinement with said slot adapted to receive the ends of said locking members.

3. The combination with a rolling window screen, having a beading formed along its longitudinal edges and locking members mounted transversely of the lower end there-I of, of guide-ways attached to the sides `of a window frame comprising superimposed strips, the inner marginal edge of the lower strip being bent outwardly and the inner marginal edges of the upper strip being bent outwardlyv and inwardly, said edges of the lower and upper strips being spaced apart to provide a longitudinal slot, the outwardly bent portion of the upper strip having a series of openings in alinement with said slot, to receive the ends'of the locking members.

4. The combination with a rollingwindow screen having locking members mounted transversely of the lower and thereof, of guide-ways attached to the sides of the window frame, each composed of superimposed strips, the outer strip having its inner edge bent outwardlyy and inwardly to provide a longitudinal slot between the strips to receive the screen edge and thelocking members, the outwardly bent portion of said outer strip having a series of openings to receive the ends of said locking members.

In testimony whereof I affix my signature.

JOHN SZAKO.
